Specification of Letters Patent. Application filed July 15, 1910. serial in. 572,120.

To all whom it may concern: v 1

Be it known that I, CLINTON Bowman citizen of the United States, residing at Fostoria, in the county of Seneca and State of Ohio, have invented certain new and useful Improvements in Post-Anchors, of which the following is a specification.

This invention relates to fences, and more particularly to post anchors, and has for its object to provide an anchor by' means of which a postmay be so braced and guyed as to hold it upright in the ground, against the tension of a wire fence, or the weight of a wooden or metal fence.

-While a number of anchors of this char acter have been patented, and it is therefore not my desire to claim the broad idea of an anchor of this character, nevertheless, there have been inherent shortcomings in the anchors introduced tof'the public, whichit is an object of my invention to overcome.

I refer particularly to structures in which the fins whichbite into the earth are held in a positive predetermined position, and which are therefore such that, should one i of the fins engage a stone or other obstruction, the operation of the anchor would be seriously interfered with.

A special object of my invention 1s, therefore, to provide ananchor'in which the engaging fins are free to rotate untll they have bitten into the earth a proper distance, when they will be forced into position to securely fasten the anchor.

Another object is to provide a post anchor which may be manufactured at'a low figure, and in which the fins may he made from cheap material.

Other objects and advantages will be ap parent from ,the following descrlption, and it will be understood that changes. in the specific structures shown and described, may be made within the scope of the claims without departing from the spirit of the invention. I

In the drawings forming a portion of.

this specification, and in which like nu- -merals of reference indicate similar parts of the several views,Figure 1 is a side elevation of a three fin anchor, the fins be-' ing in expanded position. Fig. 2 is a bot: tom plan of a three fin anchor. Fig.3 is a side elevation of a three fin anchor, the fins being in folded position. Fig. 4 is a detail perspective View of one of the fins.

Fig. 5 is a view showing a two fin anchor anchors. Fig. 7 is a detail view in section showing the arrangement of the head in the modified form.

Referring 'nowto the drawings, there is follower shown a post anchor which consists of a threaded rod 10, havin an eye 11 formed at its upper end, for t e reception of the lower end of a guy wire 12. At its lower 7 T S mmama.

Fig. 6 i

end, the rod 10 has engaged therewith a nut I 13, which is fastened immovably thereupon by means of a transverse pin 14.

Loosely mounted upon the rod abovethe nut, there 1s a concavo-convex spreader plate 15, which has its convex surface directed downwardly,.;.and which has a central opening 16*receivi'ng the, rod. This spreader plate, is'circular, as shown, and

has secured thereacross at its concave surface, a transverse diametrically disposed plate '17, which has its ends engaged in notches 18 formed in the edge portion of the plate. The upper surface. of-the plate 17 isv thus flush with the peripheral edges of the spreader plate, as shown.

" The plate-17 has a central opening 19, I

which receives the rod 10, and loosely engaged upon the rod above the plate 17, there is a pipe sleeve 20, of the usual character, which is slidable and revoluble upon the rod. If desired, any suitable sleeve may be used in this position in place of'an interiorly threaded sleeve, but interiorly threaded sleeves are used in the manufacture of the anchor, being standard fitting.

A-follower head .21 is engaged with the thread of the rod 10 above the sleeve 20, this follower head having a central interiorly threaded passage 22, receiving the rod, and

a plurality of radially extending bracket portions 23, each including two spaced walls 2 1, and a connecting top portion 25. Between the walls 24 of each of these'bracket members, there is pivoted a ground engaging fin 26, this fin being movable, in each instance, in the vertical plane of the rod 10, as shown. When the follower head 21 is a considerable distance from the. spreader plate 15, the fins 26 may extend downwardly against" the rod, but, as will beseen, the rod may be rotated tov cause the follower headito move downwardly thereon, and bring the under faces of the fins into contact with the upwardly directed edge of the Spreader plate 15, when the free ends of the fins will be directed outwardly and brought into engagement with the walls of the hole in which the .follower head consists of a in which the anchor is of course placed, and forced into the earth surrounding the hole. The sleeve 20 acts as a stop for the follower head to prevent downward motion the major transverse dimension of the plate,

and which provide, thus, thickened stems which are engaged between the walls 24 and have passed therethrough pivot pins 27 asillustrated.

In Fig. 5 there is shown a two fin anchor,

metallic plate bent longitudinally to bring its side portions into parallel relation, these side portions being connected by'an upperbight portionC, having an inner transverse dimension less than the diameter of the rod 10. A hole sufliciently large to receive the rod is formed through'the bight- C, as indicated at D, and this hole is threaded,

the threads being also cut in the inner sur-. faces of the side portions 24 of this follower head so as to give a long bearing for the re K What is claimed'is:

1. A post anchor comprising a concavoconvex plate having a central opening, 'a'

diametrical plate secured across the concave 'side of the first named plate, said diamet- 'rical plate having an opening alining with the opening of the. first named' plate, a threaded rod engaged through the two openings, a confining nut engaged with the rod. -below the convex side of the first named plate, a sleeve loosely mounted upon the rod and resting upon the diametrical plate,

a follower head threaded upon the rod above the sleeve, said follower including a plurality of spaced'ears, and fins pivoted at their inner ends between the ears, said fins having arcuate under surfaces arranged to engage against the edge of the concavoconvex plate for outward movement of the I fins when the follower head is moved in the direction of the sleeve, said sleeve being'arranged to receive the follower head thereagainst to limit the movement thereof. 2. A post anchor including a threaded rod, and a follower head mounted upon the rod,-. said follower head being formed of'a metallic plate bent upon itself to produce spaced side portions and a connecting bight, the space between the side portions being less than the transverse dimension of the threaded rod, said bight having an opening formed therethrough, said opening and the inner faces of the walls bein threaded for engagement with the threads rod.

3'; A post anchor comprising a concavoconvex plate havlng a central 'openmg, a

diametrical plate secured across the convex side of the first named plate, said 'dia: metrical plate having an opening alining with the opening of the first named plate, a threaded rod engaged through the two openings, means for holding the threaded rod 'against withdrawal from the openings, said-means being engaged with the threaded rod atthe'convex side of the plate, a follower head 1 threaded upon the rod above the sleeve, said follower including a plurality. of spaced ears, and fins pivoted at their inner ends between the ears, said fins having arcuate under surfaces arranged to engage against the edge of the concavo-convex plate, for outward movement 'of the fins when the follower head is moved in the direction of the concavo-convex plate, said threaded rod being rotatable with respect to said plate to move the follower head thereupon.

In testimony whereof I 'afiix my signa-- ture, in the presence of two witnesses.

CLINTON BOWEN.
